alex_duf··on Pop OS 24.04 LTS Beta
Ah thanks, I was so confused
alex_duf··on Pop OS 24.04 LTS Beta
right click -> "always on top". That's available by default

I don't understand, on Gnome when you maximize a window (drag to top) you can still see the time.

Now if you're talking about complete fullscreen, like when watching a video, I' don't understand the use case. Either you want fullscreen or you don't?

alex_duf··on UUIDv7 Comes to PostgreSQL 18
UUIDv7 makes sense when a distributed system needs to insert vast amount of data that will be consumed chronologically. Typically an event log table.

Anything else, as you're rightly pointing it out, is a bit of a stretch.

alex_duf··on Liberté, égalité, Radioactivité
The article describes how France helped China reach that point. I did not know that.

I guess in a beautiful world we'd have hardware accelerated, patent free codecs.

Which is almost what AV1 is, native hardware decoding is slowly slowly progressing

I remember discovering Bonobo (the British producer) because one of the devs of songbird recorded a video that showcased the features looking at a site that played Bonobo.

15 to 20 years later and I've seen him live 5 times

alex_duf··on Mirage 2 – Generative World Engine
It looks gorgeous and surreal, but it doesn't seem to be able to keep the world consistent.

Because the JVM is fairly dynamic so it becomes hard to know which part to prune
alex_duf··on The ultimate meeting culture
I've done that both in France and the UK. Nothing happen and I got some time back
alex_duf··on Lead GrapheneOS developer was forcibly conscripted into a war
software is a useful skill during a war. The same way you probably wouldn't send a doctor to a fight as the doctor is more useful to help with the wounded, a software engineer with an infosec background(as I assume the lead dev of graphene would) could be extremely useful to the war.

See also the Scottish company Orbital Marine Energy with their really cool floating design: https://o2-x.orbitalmarine.com/

I believe they specifically designed it to simplify maintenance

alex_duf··on Solar power has begun to transform the world’s energy system
>I highly doubt that we will have global negative emissions (CO2 capturing) within the next decades

Just to clarify what I wrote, I also highly doubt we'll get it at scale in the near future. We desperately need it though, as well as any other measure that will bend the trends in the right direction.

This may not be the right place for this, but I'm honestly getting very anxious about our climate. Some of the data such as the temperature anomaly is showing an exponential trend. See the scariest graph I've ever seen here: https://www.nytimes.com/2025/06/26/climate/climate-heat-inte...

alex_duf··on Solar power has begun to transform the world’s energy system
I see, thanks for clarifying I got confused there.

I didn't mention any shrinking. I just said we'd passed the CO2 per capita peak.

https://ourworldindata.org/grapher/co-emissions-per-capita?c...

This means for any human being we are emitting less carbon than we use to. It's not a big win but I'll take any good trend at the moment.

>whether the growth of renewables outpaces the depletion of our carbon budget

I'm not sure I understand. There's no carbon budget, any carbon that we emit is carbon we'll have to re-capture somehow and the longer it stays in the atmosphere the longer it will have a heating effect.

I think renewable have accelerated to the point of matching the electricity growth worldwide: https://ourworldindata.org/grapher/electricity-production-by...

We've also passed the peak of CO2 per capita, but since the population is still growing we are still increasing carbon emitions worldwide. It's going to be a while before we stop emitting anything, and then longer before we start re-absorbing it...

alex_duf··on IKEA ditches Zigbee for Thread going all in on Matter smart homes
> It did always feel a bit awkward having Zigbee networking and IP networking competing over the same site

Funny, to me that's a feature. It makes the threat of a hacked device that exfiltrate data from within your network much less likely. I avoid any wifi device because of that.

alex_duf··on François Chollet: The Arc Prize and How We Get to AGI [video]
If the incentive is there, the technology will advance. I hear "we need to slow down the progress of technology", but that's misunderstanding _why_ it progresses. I'm assuming the slow down camp really need to look into what's the incentive to slow down.

Personally I don't think it's possible at this stage. The cat's out of the bag (this new class of tools are working) the economic incentive is way too strong.

alex_duf··on Resurrecting a dead torrent tracker and finding 3M peers
Interestingly they put the infohash of the show in the URL. So one can use that website to pick which show to download just by using the hash + DHT

Edit: Nope I'm wrong, different type of hash it seems...

alex_duf··on Encapsulated Co–Ni alloy boosts high-temperature CO2 electroreduction
I'm not a chemist, so I'm failing to see the implications.

Has this got any chance of reducing our CO2 footprint?

alex_duf··on The X.Org Server just got forked (announcing XLibre)
ok, why? any grand plan? what's the background and why would anyone bet on X.org when wayland has been ok for a decade now?

alex_duf··on How much energy does it take to think?
I'd be concerned about the side effects. Sounds like burning the candle by both ends
alex_duf··on Changes since congestion pricing started in New York
I think citymapper ran an experimental private bus line because they had identified a gap. But their article doesn't have a date, and I seem to remember this was years ago, so not sure where it's at.

alex_duf··on OpenSearch 3.0 Released
It works with some caveats. I've seen it handle searches with millions of documents no problem, but the KNN search requires to load the entirety of the embedding graph in memory. So watch your RAM consumption.

The quality of your results will depend mostly on the quality of your embeddings

alex_duf··on Evidence of controversial Planet 9 uncovered in sky surveys taken 23 years apart
700 times further => isn't it farther rather than further?

Non native english speaker here, but last I checked further was a metaphorical distance, when farther was a literal distance. You can push a concept further, but you walk farther right? Or did I miss something?

alex_duf··on Deepfake porn is destroying real lives in South Korea
Sure, I mean using force and coercion is one way to obtain what you want!

Not sure that's the society I want my daughters to live in though, maybe there's a way to have both equal rights and promote family values?

Like having access to healthcare, reduce the social stigma of being a parent, ensuring there's support for new families, keeping the cost down... Etc!

alex_duf··on Millions are visiting the European Alternatives site. What trends are we seeing?
There's this interview (in french) of a French cloud company CEO here: https://www.youtube.com/watch?v=z9y5eiNYhD8

The interesting part is when he deplores the lack of support between local actors, where instead of pulling each other up, everyone plays in their corner.

I love the idea of peertube, the technology works, but getting it to gain traction is impossible. There's this catch 22 of no view => no content => no view which is really hard to break. And where VC funded platform can buy content to kick start the process, this one doesn't have any mean of kick starting it.

Maybe we should raise money to pay popular creators to publish on these peertube instances.
